PTMs (Post-Translational Modifications) are an important consideration in research. They contribute to a variety of biological activities and affect protein structures and cellular functions. Protein phosphorylation, methylation, and acetylation are the most common types of modifications of the more than 200 different attached modifications known to exist in vivo.

Site-specific antibodies have a number of potential applications: cell signaling, protein structure, function, development, maturation, localization, disease diagnostics, activity, etc. Over the years, ABclonal has developed thousands of custom site-specific antibodies.

Modification Types

ABclonal provides services on the following custom modification antibodies.

  • Phosphorylation: Citrullination, Prenylation, Glycosylation
  • Acetylation: Succinylation, Sumoylation, Biotinylation
  • Methylation: Alkylation, Tyrosine Sulfation, Polyglutamylation
  • Ubiquitination: Isoprenylation, Tyrosine Nitration, Other PTMs
  • Others: DNA methylation, RNA methylation, Panacetylation, non-histone modification, and other custom specific modified antibodies that are developed to meet your research needs.
